  • STI Roctane XD Radial Tire

    Santa (me) brought these for me last year and even though they have some chunks taken out of the lugs they're still 95% there. They have handled every kind of rock crawling you can throw at them and have yet to leave me stuck. Roctane will probably be my go to from now on.

    STI Black Diamond XTR Radial Tire

    Curt in ID

    Excellent tire for the price

    Great tires so far. A little slick on hard surfaces until I adjusted air pressure. Surprised that the heavy lugs smooth out at very low speed and handle great. Snow will be the real test. Hoping they will get me where I need to be in November

    Garrett in KS


    I have a 2004 Yamaha Warrior. You can't find a tire of this quality selling for this price anywhere else. *Rocky Mountain takes care of their customers. I ordered the wrong size and the customer support/service was refeshingly helpful in processing my return. Will definitely be ordering through these guys for a long time!
